MACHINE FOR STICKING- PINS.

To all Iwhom t may concern Be it known that we, JOHN J. Hown and TRUMANPIPER, of Derby, in the State of Connecticut, have invented a certainnew and useful improvement in the machine for sticking pins in sheets ofpaper or other substances to facilitate the handling of them in theprocess of japanning, but which may be employed in o-t-her processes;and we do hereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawings,making part of this specification, in which- Figure 1 is a plan of themachine; Fig. 2, a side and Fig. 3 a front elevation thereof; and Fig. 4a vertical section taken at the line A, a of Fig. 1.

rIhe same letters indicate like parts in all the figures. v

The principal object of our said invention is to stick pins in sheets ofpaper, or through holes in a plate and then in the sheets of paper, thatthe pins may project from the surface thereof at right angles or nearlyso, preparatory to japanning them by a process for which we contemplatemaking application for Let-ters Patent of even date with thisapplication, but the sticking of pins by our said invention mayfacilitate other processes in the manufacture of pins; and our saidinvention relates to an improvement of the machine for which LettersPatent of the United States were granted to Samuel Slocum on the 30thday of September 1841, for sheeting pins, and our said improvementconsists in combining with the groove or grooves for separating orspacing the pins and guiding them, and the follower, or equivalenttherefor for pushing forward the pins in the guide groove or grooves theemployment of a sliding frame or carriage for holding` and shifting asheet of paper or equivalent substance at right angles or nearly so,with the guide groove or grooves, whereby the pins are properly spacedin two directions and inserted in the sheet at right angles or nearly sowith the surface thereof; and o-ur said improvement also consists incombining with the combined guide groove or grooves, follower and frameor carriage for holding and shifting the sheet of paper, a perforatedplate placed in front of the sheet of paper so that at one and the sameoperat-ion the ed around the edges thereof.

pins shall be inserted through holes in the said plate and into thesheet of paper.

In the accompanying drawings a` represents a channel way between twobars o b in which the pins hang with their heads on the edges of thebars which are inclined to enable the pins to run down by gravity, andthe lower end of the said bars are curved to gradually turn and deliverthem one by one in a horizontal position into a series of parallelgrooves c made in the face of a plate CZ. This plate slideslongitudinally on suitable wags e, c on the table f, and is providedwith a handle g with which an operator slides it under the column ofpins in the channel way a that a pin may be deposited in each groove c.If pins should fail to enter in any of the said grooves as the plate ismoved forward they will do so as the plate is drawn back to the positionrepresented in Fig. 1.

By the side of the plate (l there is an open frame L adapted to slidevertically in suitable ways z', z' attached to the table, and extendingabove and below it, the table being cut out to permit the open frame tomove up and down therein. To the back of the open frame L and attachedto the upper and lower part thereof and standing out some distance fromthe back of the said frame is a vertical bar '7' into which a dog orpawl 7c catches to hold the frame at any desired elevation; and belowthe table there is a. ratchet hand or pawl Z jointed to a crank m. on ahorizontal rock shaft nmounted in suitable boxes which rock shaft isprovided with an arm 0 connected with the working levell 79 of theapparatus by means of which the shaft is turned or rocked to make theratchet hand or pawl Z act on the ratchet teeth of the bar j for thepurpose of elevating the frame to the extent of one ratchet tooth ateach operation.

The bars of the open frame h are rabbeted on that side next to thegrooved plate in which the pins are deposited, and these rabbets areadapted to receive a metal plate g with the edges of a sheet of paper 1'fold- After the plate has been inserted, with the sheet of paper it isconfined by a turn button s or other suitable means. In this way thesheet of paper is firmly held in a distended state on theback of theplate g. This plate is pierced with parallel rows of holes, the distancebetween the several holes in each row corresponding with the grooves inthe plate d, and t-he distance between the several rows correspondingwith the size of the ratchet teeth on the bar j. The holes in this plateare of a size to receive the barrels or Shanks of the pins freely butnot to permit the heads to pass through. After the pierced plate g witha sheet of paper on the back has been put and secured in the verticalsliding frame, and the frame let down so that the upper row of holes inthe plate shall be on a level with t-he grooves in the plate d, and theratchet hands or pawls put in place in the ratchet bar ,7' the attendantslides the grooved plate Z forward and back underthe channel way a tocharge the grooves with a row of pins which are thus arranged at equaldistances apart, corresponding to, and with the points toward and levelwith the upper row of holes in the plate g. The whole row of pins isthen forced forward through the holes in the plate g and into the sheetof paper behind it, by a follower' t which slides in suitable ways u, u,u, on a level with the upper surface of the grooved plate cl, and whichis operated by the arm o of the before described lever p operated by thehand of the attendant. The extent to which the pins are inserted in thesheet of paper can be governed by a gage or by the judgment of theoperator. As the pins are pushed forward by the follower they are guidedby the grooves c in the plate (Z, and as the points pass through thesheet of paper it is sustained by a grooved bar a: back of the framewhich holds the sheet of paper.

As the lever p is moved back to withdraw the follower the ratchet handor pawl Z acts on the ratchet bar and lifts the frame t with the piercedplate and sheet of paper elevating the row of pins and presenting thenext row of holes in the plate on a level with the grooved plate ci tostick another row of pins. In this way the operation is repeated untilthe whole sheet of paper is stuck with pins having the heads on one sideand the points on the other.

It will be obvious from the foregoing that instead of sticking oneentire row at each operation, the pins may be stuck one at a time bygiving a lateral movement either in the vguide groove or to the framecarrying the sheet of paper, but the mode of construction first abovespecified and represented will be found much more expeditious; and itwill also be obvious that if desired the second part of our inventionmay be dis'- pensed with by substituting for the erforated plate someother mode of hol ing the sheet of paper in the frame; but as theperforated plate facilitates the sticking of the pins in the paper andthe management of them in the processes to which they are subjected whenso stuck we prefer to use both parts of our invention in connection.

We do not wish to be understood as limiting ourselves to the specialconstruction and arrangement of the parts as equivalent constructionsand arrangements may be substituted within the range of our invention.

What we claim as our invention and desire to secure by Letters Patentis- 1. In combination with a guide groove or grooves and a follower,substantially as specified, the employment of the sliding frame forholding and shifting the sheet of paper, substantially as described,that' the pins may be properly spaced and inserted in the sheet of paperat right angles or nearly so with its surface, as set forth.

2. And we also claim in combination with the guide groove or Grooves,follower and holding and shifting frame, substantially as and for thepurpose specified, the employment of a perforated plate, substantiallysuch as described, and interposed between the guide groove or groovesand thesheet of paper held in the frame, that the pins may be insertedsimultaneous in the plate and in the sheet of paper, as set forth.`
